High speed of F2.8 and outstanding image quality

The SIGMA 18-50mm F2.8 DC DN Contemporary covers the focal length range between 27 and 75mm (equivalent to 35mm format) - with a continuous aperture of F2.8, making it ideal for portraits and close-ups where you want to crop the subject against a blurred background that does not distract from the subject in focus thanks to the attractive, soft bokeh.

With three high-precision, bright-pressed aspheres and a reduction in the total number of optical elements, the lens achieves outstanding image quality with low weight. The in-camera correction of optical disturbances also helps to eliminate aberrations such as distortion and vignetting. This performance is made possible by the advanced lens development technology at SIGMA's sole manufacturing facility in Aizu, Japan, where all SIGMA lenses are produced.

Exceptionally light and compact - ideal for mirrorless cameras

The SIGMA 18-50mm F2.8 DC DN Contemporary is remarkably light and compact, making it the perfect complement to mirrorless APS-C cameras. It is the perfect standard zoom, ideal for everyday use and suitable for a wide range of shooting situations. The lens has a maximum diameter of 61.6mm, a length of 76.5mm and a weight of 290g, while maintaining a constant aperture of F2.8.

To keep the weight low, SIGMA has constructed the lens from specially selected materials. The lens barrel is made of the polycarbonate TSC (Thermally-Stable-Composite), which is slim and robust and, above all, has a thermal conductivity similar to that of aluminum. This ensures high reliability and smooth operation in changing temperatures. For some internal components, SIGMA deliberately opted for metal, as these parts require less material while being stronger. The lens is therefore designed to withstand intensive use.

Suitable for a wide range of shooting situations

The SIGMA 18-50mm F2.8 DC DN Contemporary has a fast and almost silent autofocus, which makes it suitable for a wide range of photographic applications, including shooting in quiet environments and taking videos and photos that require fast focus tracking. This is achieved by using a stepper motor to drive the focus. As the lens is small and lightweight, it can be used very flexibly in situations that require high mobility, or when shooting from hard-to-reach shooting positions, gimbal shots, one-man video recordings and vlogging.

The lens was developed with a wide range of applications in mind, so SIGMA has chosen a design with a closest focusing distance of 12.1cm and a maximum magnification of 1:2.8**, which makes it ideal for close-up photography.

The 18-50mm F2.8 DC DN Contemporary, which combines compact dimensions, low weight, high performance and high speed, can handle a wide range of tasks, primarily with entry-level mirrorless models in both photography and video recording, but also with full-frame cameras.
